>>2.  Make sure that the entire aileron LE (where the weights are attached)
is STIFF as can be.  You must not be able to flex this area at all
otherwise, the aileron will vibrate in flight.  Most have added half-moon
ribs to accomplish this (same method used for the flaps, however you must
make sure water cannot accumulate in the mid sections, drain holes will have
to  be drilled).  On my setup, I only installed one half-moon rib, right in
the middle plus another 2-bid on the entire length of the LE... >>

Sounds reasonable.  What would you think of a 2-bid that would go straight
from the top of the weight and extend back on the aileron surface.  It would
be suspended in space, but not for very far, so it should be reasonably
stiff (could still buckle in compression, I suppose) and would certainly
stiffen the structure in beaming.  The weight isn't much of a consideration
as it is ahead of the hinge point.  Just a thought.
